3 Claims. .(Cl. 257159) The invention relates to improvements in radiators and particularly to that type which involve the use of chambers connected with each other through the medium of fluid conducting tubes,

the radiator beingdesigned to be'located in a casing, the latter having an opening at the upper and lower portion thereof whereby air may cire culate through the radiator into the casing and be discharged'in a heated condition-from the casing. W

The invention has as its principal object the provision of means for controlling the circulation of the heating medium through the radiator, which means may be conveniently manipulated from the exterior of the casing.

It is a further object of the invention to employ one of the chambers above referred to as a valve body and to provide an opening in said chamber for the reception of a closure, the closure having a valve and stem associated therewith adapted to be inserted as'a unit in the opening of the chamber into cooperative relation with the fluid inlet opening.

It is an'object of the invention-to provide a chambered member having a fluid inletand a valve for controlling flow of the heating medium through said inlet, the chamber having means combined therewith and cooperatively connected with the valve for actuating the valve, the means for actuating the valve being'preferably located exteriorly of the chamber and the valve being capable of introduction and removal from the casing and relatively to said actuating means, should this at any time become necessary or desirable.

Another object of the invention is to arrange the fluid inlet opening'o-pposite the opening for the closure so that the openings may be threaded or otherwise operated upon as for instance, to provide an opening with a valve seat.-

It is a further object to provide means for manipulating a valve having either a longitudinally movable or non-rising valve stem, the means permitting actuation of the valve from the exterior of the casing.

The invention has these and other objects, all of which will be more readily understood when read in conjunction with the accompanying drawing which illustrates various arrangements which may be employed, it being therefore obvious that additions andchange's may be resorted to without departing from the spirit of the invention as expressed in the appended claims forming a part hereof.

In the drawing, Fig. 1 is a vertical sectional view of a radiator casing having a radiator located therein, the latter having means for controlling flow of a-heating medium therethrough;

Fig. 2 is a sectional View taken on line 2--2 of Fig. 1;

Fig. 3 is a section ta and Fig. 4 is a sectional view showing a fragmentary portion of the chamber having a valve, the stem of which is of a non-rising character. v

Fig. ,5 is a section taken on line 55 of Fig. 1. In the embodiment of the invention illustrated in the drawing, a casing, 10 is contemplated having an air inlet opening 11, and an air outlet opening 12 located adjacent the opposite end thereof. A- radiator generally designated 13 is located in the lower portion of the casing, it being understood that the radiator has a fluid inlet pipe 14 and an outlet pipe 15 connected therewith to provide for circulation of the heating medium through the radiator generallydesignated 13. The radiator illustrated includes a pair of chambered elements generally designated 16 and 17 which are connected with each other through means of the tubular elements 18 which provide connecting passages between the-chambers 16 and" 17. Each of these chambers may be supplied with heat radiating fins such as 19 which will add to the efiiciency of the devices and utilize a space otherwise rendered useless. 5

As before stated, it is an object of the invention to provide a. structure such as that just referred to with means for manipulating the valve for controlling flow of fluid through-the supply pipe 14. To this end, a mechanism generally designated 20. is mounted in unitary relation with'one of the chambered elements such as 16, the mechanism being located exteriorly or" the chamber and provided to manipulatea valve mechanismgenerally designated21 which is removably mounted in said chamber.

The chambers 16 andgl'l have a wallthereof provided with a plurality of openings 22 into which thetubes 18 are inserted to complete a connection with said chambers. The chambered element 16 withwhich the inlet pipe 14 is connected is provided with an opening 23 for the reception of the inlet pipe 14 and said chamber is further provided with a valve seat 24. which is located at the inlet opening 23 and provided in a wall 25 of the chamber. The wall 26 of the chamber which is located opposite the wall 25 is also provided withan opening or aperture 27, the latter being employed for the reception of a closure such as 28 having one end of a 10 60.. en on line 3-3 of Fig. 2;

distendable and contractable bellows-like tubular member 29 connected therewith, it being understood that the opposite end of the bellowslike member is connected with the stem 30 of a valve 31 and that the stem 30 projects through the closure 28 so that an end thereof may be engaged by the mechanism generally designated 21 for manipulating the valve from the exterior of the casing.

The particular structure shown in the drawing for actuating the valve is most clearly illustrated in Fig. 3 and may include a shaft 32,

mounted for rotation in the lug 33, a hand wheel 34 secured to the shaft 32 to rotate said shaft and an eccentric or cam 35 which engages the stem of the valve. It is understood that the shaft 32 extends beyond the casing 10 so that it is accessible for use for operating the valve 31. The shaft is held relatively to the lug 34 by means of the pins respectively designated 36 and 37.

It will be noted that the closure 28, the distendable and contractable diaphragm 29, valve and valve stem 30 are connected in unitary relation with each other so that should replacement of the valve become necessary, this may be conveniently accomplished merely by removing the pins and shifting the shaft 32 so that the closure 28 may be unscrewed from the chambered member. It will be further noted that the opening 23 for the reception of the inlet pipe 14 is located diametrically opposite the opening 27 in which the closure 28 is arranged and thus the valve seat and the openings are readily accessible during manufacture of the device to apply the threads to the openings or apply or face the valve seat.

As before stated, it is contemplated to use a valve having a non-rising valve stem such as that indicated by the numeral 39. In the construction shown, an annular sleeve 45 is screwed into the wall 26 of the casing with a portion projecting slightly at the outer face thereof, and a cap 46 is screwed onto this projecting part to rigidly lock the sleeve 45 in position. The cap 46 is provided with a central bearing for the stem 39, and in the form shown also rigidly secures the plates 4'7 and 48 in position between the end of the sleeve 45 and the cap, The plate 47 is provided with an annular offset part or recess at its center adapted to receive a fixed collar 49 upon the stem 39 and to thereby cooperate with the plate 48 to prevent longitudinal movement of the stem when in service.

As shown the sleeve 45 is threaded upon its interior and the threaded element 40 is fitted into the sleeve 45 so that rotation of the element 40 will produce a corresponding longitudinal movement between the sleeve and element. As shown the element 40 is provided with a central axial recess adapted to receive the stem 39, said element also having diametrically arranged grooves in its walls adapted to receive and cooperate with the projections 50-50 upon the stem 39 so that by rotating the stem 39 the element 40 will be rotated and thereby move longitudinally as may be desired.

As shown the valve 41 is rotatably mounted upon the end of the member 40 and the longitudinal position of the member 40 therefore controls the position and operation of the valve 41. Any desired means for rotating the stem 39 may be employed, that herein shown involves the use of a beveled gear 42 which meshes with a beveled gear 43 secured to the rotatable shaft 44, the latter of which may be mounted in a lug similar to the lug 33 shown in Fig. 3.

From the foregoing description of the invention, it is manifest that a radiator comprised of a pair of chambers which are connected through the medium of fluid conducting tubes and adapted to be located in a casing is provided with a simple means for manipulating the valve from the exterior of the casing. It is further evident that the inlet opening to the chamber and the opening provided for the reception of the valve mechanism are aligned with each other so that they may respectively be readily provided with means for the reception of a valve and its associated parts and a fluid inlet pipe and that the arrangement is such that the valve element and its associated parts may be removed from the chamber as a unit when this becomes necessary or desirable.

Having thus described the invention, what I claim as new and desire to cover by Letters Patent is:

1. In a radiator, a chambered element adapted to operate as an inlet manifold and having substantially parallel side walls with aligned openings extending therethrough, a removable valve seat and an inlet pipe attached to one of said openings and a removable closure mounted in the other opening in combination with a valve mounted upon said closure adapted to cooperate with said valve seat, means rotatably connected with said valve and cooperating with said closure for moving the said valve means extending through said closure for controlling said valve, and means between said closure and said valve for preventing the escape of the heating medium between said closure and said valve controlling means.

2. In a radiator, a chambered element adapted to operate as an inlet manifold and having substantially parallel side walls with aligned openings extending therethrough, a removable valve seat and an inlet pipe attached to one of said openings and a removable closure mounted in the other opening in combination with a valve mounted upon the said closure adapted to cooperate with said valve seat, means extending through said closure for controlling said valve and means between said closure and said valve for preventing the escape of the heating medium between said closure and said valve controlling means and a part rotatably mounted upon said element for actuating said valve controlling means.

3. In a radiator, a chambered element adapted to operate as an inlet manifold and having substantially parallel side walls with aligned openings extending therethrough, a removable valve seat and an inlet pipe attached to one of said openings and a removable closure mounted in the other opening in combination with a valve mounted upon said closure adapted to cooperate with saidvalve seat, means rotatably connected with said valve and cooperating with said closure for moving said valve means extending through said closure for controlling said valve, and means between said closure and said valve for preventing the escape of heating medium between said closure andsaid valve controlling means, and a part rotatably mounted upon the said element for actuating said valve controlling means.
